Key words: supercritical fluids, micronization, water-soluble salts

Supercritical fluid micronization of water-soluble salts with supercritical carbon dioxide targeted on to fabrication of submicron and nanosized particles is experimentally studied using NaCl and NH4NO as examples. A parabolic-type size distribution of resulting salt particles on CO2 pressure at 80 °C is determined. Minima of mass-average particle sizes (0.14 rm and 0.42 rm for NaCl and NH4NO respectively) are reached at CO2 pressures in the range of 7.5—10 MPa.
